Type II Silt Barrier

Type 2 Turbidity Curtain for Moving Water

type II silt barrierTriton Type II Silt Barrier is floating turbidity curtain designed specifically for areas with moving water, currents, waves, or tides. Manufactured in the USA with high quality reliable components, Triton Type 2 Silt Curtains contain turbidity and displaced particles in a designated area. Triton Type 2 Turbidity Barriers are recommended for use in water locations with waves up to two feet (2'), moderate wind, and currents up to 1 knot.

Type II Silt Barrier Accessories

marine buoy accessoriesAnchor Kits: Anchoring is crucial for the success of your project. Without proper anchoring your Type 2 Turbidity Barrier WILL fail.

Buoys and Marker Lights: Buoys and Marker Lights are used for demarcation and will help you in compliance.

Tow Bridles: Tow Bridles help distribute weight and prevent damage during deployment and adjustment.

Accessories are an important component for the installation of any silt curtain or barrier. Click the link above to Learn more about these Type II silt curtain accessories, their specs, and uses. View our Ground Anchor Installation and Silt Curtain Anchoring Instructions.

Importance of Turbidity Curtain Anchoring: Anchor kits and anchoring are one of the most important accessories for floating turbidity curtains in sites dealing with moving currents, waves, tides, or other site factors. Having the right anchor pattern, installation design, and anchors can significantly influence, reduce, and redistribute loads placed on your barrier and increase curtain life span. Contact our technical team at 1-772-646-0597 for more information regarding anchor placement and use.

Turbidity Curtains and Saltwater Considerations

floating turbidity curtainsWhen using the Triton type 2 silt barrier in saltwater applications, careful consideration should be given to the tension cables and connectors. The following component adjustments are recommended for any location with saltwater:

  • Stainless Steel Cable
  • Zinc Anode Connectors

For short term projects, galvanized components can be used for a period of up to 12 months.

Silt Curtain Fabric Considerations

Alternative fabrics are also available for extended deployment in areas with high pH levels, high or low temperatures, or in areas where chemicals are present.

DOT vs. Heavy Duty (HD) Silt Curtains

turbidity barrierThe main difference between the contractor/DOT silt curtains and the HD models are in terms of the fabric and section connectors. Contractor Silt Barriers feature a top connector plate, while HD models feature a full slide connector between each section. Depending on how much stress is placed on the curtain, different options may be better than others for your location.

  • Base Fabric
  • Top Tension Cable
  • Universal Connector or Steel Plate
  • Bottom Stress Plate
  • Bottom Ballast Chain

When to Use a Permeable Silt Curtain?

Permeable Type 2 Turbidity Curtains are most commonly used when they are specified in a site project or when the curtain will be dealing with a significant amount of water pressure. The bottom filter panel will help reduce pressure on the curtain by allowing water to continue to the flow the curtain.

Turbidity Curtains and Water Conditions

How a Turbidity Curtain Works: The main function of a silt screen or turbidity barrier is to control the dispersion of suspended silt and other particulates to improve settling times (Stokes Law). During a construction project, silt and other materials often become suspended in the water area. Silt curtains are placed within the water to create a confined zone for the contained materials. These contained areas allow marine contractors to stay within Federal and State Clean Water Act and NPDES Phase II regulations. In turn, this helps sites to avoid fines and allows projects to be completed on time.

Please note, turbidity curtains are designed to act as a temporary area that increases the amount of time solids have to settle back down to the bottom of the area. They will not act as dams or walls.

Silt Curtain Water Conditions, Factors, and Considerations

triton turbidity curtainConsideration of site and water conditions is an important step for any location looking to control silt in a moving water body. Due to the current and waves in these areas, additional pressure is placed on the barrier during use. In order to accommodate and contain silt in these conditions while choosing which floating silt barrier to use, it is important to consider the following:

  • Water Velocity
  • Wave Height and Frequency
  • Wind Speed and Direction
  • Tides
  • Soil Type
  • Project Duration

Knowing these elements can help determine the right anchoring strategy, curtain model, and deployment method. Read a customer question about whether using an Impermeable Turbidity Barrier is right for their site.
